Hi, I've two pcvc740, Main Board asus a7v33 with via333
and 4 USB devices on the main board.

The problem was that average 3 per 4 times :-(((  when I powered on the
machine
and loading Linux the computer hanged up when init.d was loading.
Exactly, 1X seconds after UHCI was loading.

I remove USB from init.d, and loading from console (modprobe)
and it hanged up too.

I was trying to solve this problem one week and I solved it.
2 cameras pcvc740 should be connect to the same USB device 
(Every USB device has 2 USB ports on asus a7v333)
When both are connecting to the same USB device it never hang up.

I'm completely sure (I'm trying - both cameras on the same device => 30-40
restart =>
Never hang up. I connected the cams on different USB device, average hang
up 3 per 4 times
When loading UHCI(*)) that there is the problem, but I don't understand
why.

(*) but when it was lucky and loading 1 per 4 times (average) it didn't
hang up later when
computer was working 

So, I think it is a problem, because when I have both cams on the same
device
I can't use both in 640x480
